Verified step by step guidance1
Understand the different zones of a lake: Littoral, Limnetic, Profundal, and Benthic.
The Littoral zone is the area near the shore where sunlight penetrates all the way to the sediment, allowing aquatic plants to grow.
The Limnetic zone is the open water area where sunlight does not reach the bottom, but is enough for photosynthesis to occur.
The Profundal zone is the deep part of the lake where sunlight does not penetrate, typically found in deeper lakes.
The Benthic zone is the bottom of the lake, including the sediment surface and some sub-surface layers.
